KC, currently, has absolutely no cap room to spend on a free agent like Cobb. For the 2015 cap they are $9M over the current cap.http://www.spotrac.com/nfl/cap/2015/ (http://www.spotrac.com/nfl/cap/2015/)

Bowe is going to count around $10-$11M this next year, and I see no way they will add Cobb.

The Vikes also have significantly less money to work in FA than does the Packers.
